Last night was fashion's biggest night of the year and everyone - and we do mean everyone - was there. Screw the Oscars! For fashionistas, the Metropolitan Museum's "American Woman: Fashioning a National Identity" was the real proving ground:

There were several major trends on display. Sparkle Motion was very popular. Claire Danes' Burberry take was vaguely Medieval.

Nicole Richie, typically romantic in Marc Jacobs.

Gwen Stefani, natch, repped L.A.M.B.

And it's only fitting that SJP should rock disco-fab Halston Heritage!

Also 70s-retro: Erin Fetherston in high-sheen Mrs. Roper-chic.

Marion Cotillard in Dior.

Repping the obligatory good witches out there: Anne Hathaway in Valentino.
